Definitions

  • the present invention relates to a shielded connector in which a braided conductor is fastened and electrically connected to a shield shell by a shield ring.
  • US2002/157843A1 discloses an electric shielding structure
  • JP2001273955A discloses an antenna in-which a prevention seal is used against galvanic corrosion
  • EP2254199A1 discloses a shielding braid termination.
  • a shielded connector is used as a connector for a wire harness in a hybrid electric vehicle (HEV), an electric vehicle (EV), or the like.
  • a shielded connector includes: terminal-equipped electric wires in each of which a terminal is connected to an end portion of the wire; a housing which contains the terminals of the terminal-equipped wires; a shield shell which is attached to the housing; a braided conductor which is externally attached to the wires; and a shield ring which cooperates with the shield shell to clamp the braided conductor therebetween, and which is swaged to be electrically connectable to the shield shell (see Patent Documents 1 and 2).
  • a shielding circuit is formed by connecting the shielded connector to a case, with the result that a shielding effect is attained.
  • a braided conductor is made of copper or a copper alloy, on the other hand, stainless steel or the like having high strength is used in a shield ring. Therefore, the portion where the braided conductor is in contact with the shield ring has a bimetallic contact, and there is a possibility that galvanic corrosion may occur to reduce the shielding effect.
  • the invention has been conducted in view of the above-discussed circumstances. It is an object of the invention to provide a shielded connector in which an excellent shielding effect can be always maintained.

Even when the metal of the shield ring is different in kind from that of the braided conductor, therefore, it is possible to surely prevent galvanic corrosion due to a bimetallic contact from occurring in the place where the shield ring is swaged. Consequently, an excellent shielding effect can be always maintained, and high performance and quality can be maintained for a long period.
  • the acetate tape formed of semisynthetic fibers which are made of acetylcellulose is wound around the outer circumference of the braided conductor covered on the shield shell, and the shield ring is swaged from the outer circumferential side thereof. According to the configuration, the braided conductor and the shield ring can be satisfactorily insulated from each other in a very easy manner.
